HORSESHOE.

Application filed December 13, 1909.

Specification of Letters Patent.

Patented May 10, 191%.

Serial No. 532,795.

To all whom it may concern:

Be it known that I, GEORGE LIMBAOI-I, a citizen of the United States ofAmerica, residing in New York, in the borough of the Bronx, county andState of New York, have invented certain new and useful Improvements inHorseshoes, of which the following is a specification.

This invention relates to an improved auxiliary calk for horseshoes sothat the slipping of the horses on ice or sleet-covered streets can beefiectively prevented by giving them a good and reliable foothold on thestreet; and for this purpose the invention consists of a horseshoe tothe rear-calks of which are applied auxiliary calks provided withinterchangeable pins, and means for holding the auxiliary calks securelyin position under the horseshoe and adjacent to the rear-calks of thesame.

The invention consists further of the construction of the auxiliary calkas will be fully described hereinafter and finally pointed out in theclaims.

In the accompanying drawings, Figure 1 represents a perspective view ofa horseshoe with my improved auxiliary calk attachment, Fig. 2 is adetail side-elevation of a rear-calk of a horseshoe with my improvedauxiliary calks in position thereon, Fig. 3 is a vertical longitudinalsection on line 3, 3, Fig. at, and Fig. i is a bottom-view of Fig. 3.

Similar letters of reference indicate corresponding parts throughout theseveral news.

Referring to the drawings, a represents a horseshoe, a the toe and a therear-calks of the same. On the rear part of each arm of the horseshoe,adjacent to the rear-calks a are arranged auxiliary calks Z), which aremade of rectangular blocks, each of which is suspended from the shoe aby a pin (Z, that is provided with an enlarged head (Z at its lower endand which is passed through a hole in the forward end of the ai'lxiliarycalk b and a hole alined therewith in the shoe, as shown in Figs. 2 and3. The suspension-pin cl is upset at its upper end (Z so as to bepermanently connected thereby with the shoe (4. The auxiliary calk b isfurther provided with a number of vertical holes 0 into which areinserted headed anti-slipping pins 6, which are tapered or beveled attheir lower ends so as to form thereby sharp points 6 that extend belowthe auxiliary calks and heel-calks of the shoe, as shown in Fig. 3. Therear-end of the auxiliary calk b is rigidly secured in position by meansof a screwbolt f the threaded shank of which is passed through ahorizontal hole 0 in the rear-calk a and screwed into aninteriorly-threaded socket f in the rear-end of the auxiliary calk b.The screw f is provided with a square or other shaped head 7 so as topermit the screwing in of the threaded shank of the bolt f into thesocket or the unscrewing of the same for releasing the auxiliary calkZ). When the screw-bolt f is unscrewed and released from the auxiliarycalk b, the latter can be moved sidewise on the suspension pin (Z into aposition at right angles to the rear-part of the shoe so as to permitthe dropping in of new pins and the exchange of worn out pins for newpins. The inner faces of the rear-calks and the adjacent faces of theauxiliary calks are made arc-shaped and concentric with thesuspension-pins, as shown in Fig. 4:.

hen the streets are not covered with ice, the auxiliary calk is retainedin position on the shoe, but without inserting any antislipping pinsinto the same. But when the streets are covered with ice and slippery,the fastening screw-bolts are unscrewed from the auxiliary calks I) thelatter swung sidewise on the suspension-pins d and a. set ofanti-slipping pins dropped into the holes of the auxiliary calks. Thiscan be done by the driver while he is on his regular trip in case coldweather sets in and the streets become slippery. For this purpose thedriver carries two sets of pins with him, also a key for permitting theunscrewing of the fastening bolts and the dropping of the pointed pinsinto the auxiliary calks after moving the same in outward direction onthe shoe, after which the auxiliary calks are returned into positionunder the shoe, and locked to the rear-calks by turning the fasteningscrew-bolts into the threaded sockets of the auxiliary calks. The headsof the anti-slipping pins are held firmly in position between theauxiliary calks and the shoe, so that they cannot give while in use.When the roads are not slippery, after the melting of the ice or sleet,the anti-slipping pins 6 are removed from the auxiliary calks and thelatter replaced in position by the fastening screwbolts until theweatherchanges and it should be necessary again to insert the headed pins,which can be done either before starting out with the team or while onthe road with the same.

By the auxiliary calks and interchangeable anti-slipping pins aconvenient and inexpensive means is obtained for preventing accidents tohorses on slippery streets, without requiring the pointing up of therearcalks by the blacksmith, as heretofore.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. The combination, with the rear-ealks of a horse-shoe, of auxiliarycalks suspended from the rear-portions of the shoe, and provided withvertical holes, headed and pointed anti-slipping pins inserted into saidholes, and means attached to the rear-calks for securing the auxiliarycalks in position on the rear-calks of the shoe.

2. The combination, with the rear-calks of a horseshoe, of auxiliarycalks having vertical holes suspended from the shoe, headedanti-slipping pins inserted into the holes of the auxiliary calks, andscrew-bolts passing through the rear-calks and engaging threaded socketsof the auxiliary calks.

3. The combination, with the rear-calks of a horse-shoe, of auxiliarycalks, headed pins for suspending the front-ends of the rearcalks fromthe shoe, headed and pointed anti-slipping pins inserted into verticalholes of the auxiliary calks and extending below the same and therear-calks and heel-calks,

and screw-bolts extending through the heelcalks and engaging threadedsockets of the auxiliary calks.

4. The combination, with the rear-calks of a horse-shoe of auxiliarycalks provided with vertical holes, headed suspended pins passingthrough the rear-parts of the shoe and the front-ends of the auxiliarycalks, headed anti-slipping pins inserted into the holes of theauxiliary calks and means for securing the auxiliary calks to therear-calks, the adjacent faces of the auxiliary calks and rear-calksbeing concentric with the suspension pins for permitting the sidewiseswinging of the auxiliary calks for inserting, removing or exchangingthe anti-slipping plus.

5. An auxiliary call: formed of a rectangular block pivotally attachedon the rearpart of an arm of the horseshoe and provided with verticalholes, headed and pointed anti-slipping pins inserted into the holes ofthe auxiliary calk, and means attached to said block and said adjacentarm only for holding said block against said rear-part.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
